Back of the envelope thoughts on how it gets paid for...
Raise GST- Politically diffiult. Regressive. But could try it in some spin to boost wages/inflation (still hard).
Austerity- Ghost of 2014 haunts. Public getting a bit edgy on public services/amenities cut while population growth is insane high.
Cut CGT discount/neg gearing- Borrow an ALP idea. CGT discount more likely then neg gearing for mine. Potentially tanks housing.
Remove imputations- Would need some other compensatory relief for dividends. Potentially tanks the ASX.
Hodge podge of excise, fringe benefits, luxury car tax, whatever else etc- Won't raise enough.
Just plain lose AAA rating- Politically difficult. Would need to be hoping it occurs post election.
Absolute accounting nonsese- Back this horse. Ridiculous optomistic assumptions over the forward estimates. Probably loses the AAA mentioned above but that is the next Parliament's issue.
A mix of the politically difficult, borrowing ALP ideas and outright lies. But this government is firmly in Hail Mary territory now.
